Time machine + Airport extreme probs

[JAMAL]

Hi all, please help me before i break something!!

Having a big problem which i have been trying to sort for 4 hours! i cant get time machine to recognise my external hard drive (freecom portable) which is plugged into my AEBS.

The drive is formatted Mac OS extended (journaled) with GUID and i can see the drive in finder no problems, its mounted but as soon as i load time machine and click choose disk it isn't showing.

If i insert the disk into the usb port on my macbook it pops up right away asking if i want to use it for time machine!!! GRRRRR

HELP!!!!!

Hi Feek, yes i've done that, i may change the password and enter it again when i get back to my mac as im out at the moment, i have a feeling i've messed to much

Well i tried changing the password so i had to re enter it with now joy.

I was wondering if my usb HD wasnt recieving enough power so i formatted my usb pen drive as required and time machine wont see that either, i can use both drives as an airdisk and they mount fine.

Its really annoying me now

Feek, i have uploaded jpgs of my airport settings, could you have a quick glance to see if theres anything obviously wrong?

Cheers

I have managed to get time machine see the disk by using a command i found on macrumors.

defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1

Could this cause any issues? i'l see how it goes

Ah i thought is was supposed to work but apple wont support it. Its done about 1gb now, 35 to go............

Most people have it working right away like Feek and Lordsplodge
